About Us

Percentage Calculator is a free online tool designed to make everyday percentage maths fast, accurate, and accessible to everyone. Whether you are checking a discount, calculating a tip, comparing exam scores, or analysing financial data, our three calculators give you instant results.

Our mission

We believe that understanding percentages should not require a maths degree. Our goal is to provide a clean, distraction-free tool that works in fifteen languages and explains the maths behind every result so you can learn while you calculate.

Why we built this

Percentage questions come up constantly in daily life, yet most calculators are cluttered, slow, or locked behind sign-up walls. We wanted a page that loads instantly, works on any device, and teaches the underlying formulas rather than just handing you a number.

Free and multilingual

This tool is completely free to use and available in fifteen languages. We support our work through unobtrusive advertising, which allows us to keep every feature free forever.
